Who was studied 47,745 European ancestry individuals.
The effect
Each copy of the G allele shifted the measure 0.208 higher (95% confidence interval 0.14-0.27); p = 3 × 10−12.
How common The G allele had a frequency of about 1% in the people studied.
Where it sits Chromosome 1, band 1q23.3 — in an intron of FCRLB.
What each result means
A/ANo copy of the version the research linked to FCGR2A protein levels. This is the starting point the study compared everyone against.
A/GOne copy of the version the research linked to FCGR2A protein levels. That is a smaller link than two copies.
G/GTwo copies of the version the research linked to FCGR2A protein levels. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs145739258
What is rs145739258?
rs145739258 is a single position in the genome, in or near the FCRLB gene. Published research associates it with fcgr2a protein levels. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs145739258 linked to?
On MyGeneLog this position is linked to Celiac Disease. The research behind each link, and its sources, are set out on that condition page.
Does having rs145739258 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs145739258 come from?
GWAS Catalog, Nature genetics 2025, PMID:39789286. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
